Abstract
This disclosure is directed to an expansion band particularly adapted for use as a watch band, jewelry band, bracelet or the like in which a plurality of links are pivotally connected to each other by pins received in recesses, and means for locking adjacent links to each other with the adjacent links having size in contiguous relationship, and fin means projecting laterally from the side of one adjacent link for reception in recess means in the side of a second adjacent link whereby a gap between adjacent links is bridged by the fin means.
Claims17
An expansion band particularly adapted for use as a watchband, jewelry band, bracelet or the like comprising a plurality of links, means pivotally connecting adjacent links to each other, means for locking adjacent links to each other, adjacent links having sides in contiguous relationship to each other, fin means projecting laterally from the side of one adjacent link for reception in recess means in the side of a second adjacent link whereby a gap between adjacent links is bridged by said fin means, said pivotal connecting means including a male pivot pin projecting from the side of one link and being received in a bore of a trunnion projecting from the side of another link, and said fin means being defined by a wall common to said trunnion.
An expansion band particularly adapted for use as a watchband, jewelry band, bracelet or the like comprising a plurality of links, means pivotally connecting adjacent links to each other, means for locking adjacent links to each other, adjacent links having sides in contiguous relationship to each other, fin means projecting laterally from the side of one adjacent link for reception in recess means in the side of a second adjacent link whereby a gap between adjacent links is bridged by said fin means, said pivotal connecting means including a male pivot pin projecting from the side of one link and being received in a bore of a trunnion projecting from the side of another link, and said fin means including a pair of walls carried by said one link disposed on opposite sides of said male pivot pin and defining therewith a recess for receiving said trunnion.
An expansion band particularly adapted for use as a watchband, jewelry band, bracelet or the like comprising a plurality of links, means pivotally connecting adjacent links to each other, means for locking adjacent links to each other, adjacent links having sides in contiguous relationship to each other, fin means projecting laterally from the side of one adjacent link for reception in recess means in the side of a second adjacent link whereby a gap between adjacent links is bridged by said fin means, said pivotal connecting means including a male pivot pin projecting from the side of one link and being received in a bore of a trunnion projecting from the side of another link, said fin means including a pair of walls carried by said one link disposed on opposite sides of said male pivot pin and defining therewith a recess for receiving said trunnion, and said fin means further including a wall common to said trunnion.
An expansion band particularly adapted for use as a watchband, jewelry band, bracelet or the like comprising a plurality of links, means pivotally connecting adjacent links to each other, means for locking adjacent links to each other, adjacent links having sides in contiguous relationship to each other, a pair of fin means separated by recess means along a side of one adjacent link in registry with a pair of recess means separated by fin means along a side of a second adjacent link whereby a gap between adjacent links is bridged by said fin means, and said fin means all project laterally away from their respective link sides for reception in their respective recess means.
An expansion band particularly adapted for use as a watchband, jewelry band, bracelet or the like comprising a plurality of links, means pivotally connecting adjacent links to each other, means for locking adjacent links to each other, adjacent links having sides in contiguous relationship to each other, fin means projecting laterally from the side of one adjacent link for reception in recess means in the side of a second adjacent link whereby a gap between adjacent links is bridged by said fin means, at least two of said fin means being spaced from each other along the length of each link, and at least two of said recess means being spaced from each other along the length of each link.
An expansion band particularly adapted for use as a watchband, jewelry band, bracelet or the like comprising a plurality of links, means pivotally connecting adjacent links to each other, means for locking adjacent links to each other, adjacent links having sides in contiguous relationship to each other, fin means projecting laterally from the side of one adjacent link for reception in recess means in the side of a second adjacent link whereby a gap between adjacent links is bridged by said fin means, and said locking means being disposed in bridging relationship to said gap and within opposing aligned slots in each link sides.
An expansion band particularly adapted for use as a watch band, jewelry band, bracelet or the like comprising at least two links each having an outer surface, an inner surface, opposite end surfaces and opposite side surfaces, means for pivotally connecting said links to each other, a first of said links being disposed with a first side surface thereof in opposed spaced relationship to a first side surface of a second of said links, each first side surface being defined between an outer terminal side edge common to an associated outer surface and an inner side edge disposed between associated inner and outer surfaces, said first side surfaces defining a gap therebetween of a predetermined size when said links are generally disposed in coplanar relationship and increasing in size as said links pivot such that said outer terminal side edges move away from each other, a fin set-off in part by a surface beginning at said second link inner side edge and projecting toward said first link first side surface and across said gap, a recess set-off in part by a surface beginning at said first link inner side edge and extending away from said second link first side surface and receiving therein said fin whereby irrespective of the degree to which the links are pivoted relative to each other said gap is at all times bridged by said fin, each of said links includes an inner terminal side edge common to an associated inner surface, said pivotally connecting means being defined by a pivot pin carried by at least one of said links received in a recess of another of said links, and said fin is positioned between said pivot pin receiving recess and one of said inner and outer surfaces.
An expansion band particularly adapted for use as a watch band, jewelry band, bracelet or the like comprising at least two generally parallel oriented links each having an outer surface, an inner surface, opposite end surfaces and opposite side surfaces, means for pivotally connecting said links to each other, a first of said links being disposed with a first side surface thereof in opposed spaced relationship to a first side surface of a second of said links, each first side surface being defined between an outer terminal side edge common to an associated outer surface and an inner side edge disposed between associated inner and outer surfaces, said first side surfaces defining a gap therebetween of a predetermined size when said links are generally disposed in coplanar relationship and increasing in size as said links pivot such that said outer terminal side edges move away from each other, a fin set-off in part by a surface beginning at said second link inner side edge and projecting toward said first link first side surface and across said gap, a recess set-off in part by a surface beginning at said first link inner side edge and extending away from said second link first side surface and receiving therein said fin whereby irrespective of the degree to which the links are pivoted relative to each other said gap is at all times abridged by said fin, said pivotal connecting means includes a trunnion projecting from said second link side surface, said trunnion including a bore for receiving a pivot pin projecting from said first link side surface, and said trunnion and fin having a common wall.
